Abstract
A method of making an optical transmission tube comprises having a tubular clad and a core covered with the tube and having a refractive index higher than the clad. The core has light-scattering particles uniformly dispersed in or throughout the core, so that light passing through the core is reflected and scattered at individual scattering particles to permit the light to be emitted from outer surfaces of the clad.
